Anticoagulants—A Problem Of Distribution For The Hawaiian Sugar Industry, Allen H. Teshima

Vertebrate Pest Conference Proceedings: 7th (1976)

Current rodent control practices for the Hawaiian sugar industry revolve around the use of single grain baits containing anticoagulants in bait stations and zinc phosphide for aerial applications. Neither type of control programs as they are now applied has been very effective against the Norway rat (Rattus norvegicus) which is becoming a major problem species for the industry. As a result, we have sought a more effective anticoagulant, to which the Norway rat is more susceptible, and an improved method of bait distribution. With knowledge of the month-to-month variation in the field rodents' gestation rate, a new control …

The Cost Of Predator Damage Control Using Trapping As The Primary Control Technique, Ronald A. Thompson

Vertebrate Pest Conference Proceedings: 7th (1976)

The justification and economics of the operational animal damage control program in California as conducted by the U.S. Fish and Wildlife Service are discussed. Emphasis is given to the necessity for use of the steel trap. Nearly 83 percent of the depredators are taken by trapping. Annual agricultural losses due to predation were estimated at $4.7 million in California for Fiscal Year 1975. The projected cost-benefit ratio was 1:3.9.

The Use Of Aircraft In Predator Control, Dale A. Wade

Vertebrate Pest Conference Proceedings: 7th (1976)

Private aerial hunting of predators for protection of livestock began before 1925 in the western United States. Apparently, it was first used in professional control programs in 1942. Inclement weather, dense vegetation and rough terrain are limiting factors and helicopters are more versatile than fixed-wing aircraft. When it can be employed, aerial hunting is unsurpassed as an immediate control method where livestock losses are severe and the need for control is urgent.

Control Methods For Nuisance Beaver In The Southeastern United States, Edward P. Hill

Vertebrate Pest Conference Proceedings: 7th (1976)

Strychnine alkaloid baits were consumed by both captive and wild beaver without any apparent hesitation. An approximate minimal acute lethal dose of sodium monofluoro-acetate to beaver of mixed ages and sex was 0.202 mg/kg. Trapping beaver on four study area watersheds in Alabama with No. 330 conibear traps for approximately two weeks in winter during two successive years essentially eliminated beaver. Older individuals were trapped the first year, maturing juveniles and the remaining few adults were trapped the second year, and there was very little reproduction between the trapping periods. Trapping, with its recreational appeal, and income and food potential …

Pharmacological Review Of Chemicals Used For The Capture Of Animals, Peter J. Savarie

Vertebrate Pest Conference Proceedings: 7th (1976)

A review of the literature reveals that over 60 chemicals have been used for the capture of wild animals, but only 30 of the most widely used chemicals are discussed in the present paper. For practical considerations these chemicals can be classified as being either (l) neuromuscular blocking agents, or (2) central nervous system (CNS) depressants. Some common neuromuscular blocking agents are d-tubocurarine, gallamine, succiny1choline, and nicotine. M99 and its derivatives, phencyclidine, and xylazine are some of the more commonly used CNS depressants. Neuromuscular blocking agents have a relatively rapid onset and short duration of action but they do not …

Efficient Ci Calculations Utilizing The Symmetric Group, Gordon A. Gallup, J.M. Norbeck

Gordon Gallup Publications

Gallup has recently given a solution to the problem of determining an orthogonal representation matrix for an arbitrary permutation of the symmetric group in terms of sandwich representations. In this paper it is shown how this provides a means for the precalculation and storage of the necessary distinct coefficients needed in the construction of the various Hamiltonian matrix elements of an orthogonal orbital CI calculation. This method has the advantage over those published previously in that the spin degeneracy problem is handled more efficiently. It is shown that this procedure can be utilized with both the "construction and storage" algorithms …

Duration And Intermittancy Of Noise Exposure For The Operator Of A Self Propelled Baler, Lyle Koester, Kenneth Von Bargen

Department of Agricultural and Biological Systems Engineering: Presentations and White Papers

Evaluation of the noise exposure of agricultural machine operators requires that machine operation time and intermittancy of work patterns be determined. One method of obtaining such data is by using event activity recorders. These data are available for haying machines operated at the University of Nebraska Field Laboratory, Mead during the 1963 through 1966 seasons. Approximately 60 machine operator days per season were recorded on service recorder charts for the following machines:
1. self-propelled windrowers
2. self-propelled and pull-type balers
3. self-propelled and pull-type bale wagons
In addition some motion-time study data are available for the newer loose hay stackers …

Raman Spectrum Of Gadolinium Molybdate At 80°K, B.N. Ganguly, Frank G. Ullman, Roger D. Kirby, John R. Hardy

Roger Kirby Publications

Lines that overlap from thermal broadening in the room-temperature Raman spectrum of gadolinium molybdate are resolved in the 80°K spectrum. A total of 126 of the possible 201 lines have been resolved. Symmetry assignments are derived from considerations of both point symmetry and polariton dispersion, supported by separate measurements of A1(TO) and A1(LO) spectra. The splitting of the unstable 47 cm-1 room-temperature A1(TO) line into a doublet at 44.5 and 51.5 cm-1, observed previously only in ir absorption, is also observed in these spectra. On heating, the 44.5-cm-1 line remains fixed in frequency whereas the 51.5-cm-1 line broadens and shifts …

(R - I) Colors Of Cepheids And Yellow Supergiants In Open Clusters, Edward G. Schmidt

Edward Schmidt Publications

(R - I ) and (b - y) observations of nine Cepheids which are members of open clusters, 14 field Cepheids, and 34 nonvariable yellow giants in or near open clusters are presented. Colorcolor relations for the Cepheids are found to differ significantly from star to star. Additionally, the nonvariables may differ from the Cepheid color-color relation. Pulsational masses are determined for the Cepheids using both (R - I) and (B - V) colors as temperature indicators. For some of the shorter period stars the (R - I) masses agree with evolutionary masses, which is not the …

Some Comments On The Plasmon Spectrum Of Tetrathiafulvalene Tetracyano-P-Quinodimethane (Ttf- Tcnq), P. F. Williams, A. N. Bloch

P. F. (Paul Frazer) Williams Publications

Our random-phase-approximation model calculation of the high-frequency dielectric response of a quasi-one-dimensional metal is generalized to the case of n conducting strands per unit cell. For a model of the two-band system tetrathiafulvalene tetracyano-p-quinodimethane we obtain good agreement with recent experiments, and also predict an acoustic-plasmon branch, Some implications for the physics of the material are discussed.

Review Of The Immigrant Church: New Work's Irish And German Catholics, 1815-1865 By Jay P. Dolan., Frederick C. Luebke

Department of History: Faculty Publications

American church history, as practiced by its traditionalists, has recounted the intricacies of theological thought and debate, the mighty deeds of church fathers, and their positions on important social and political questions of the day. Despite the considerable influence of H. Richard Niebuhr's Social Sources of Denominationalism (1929), which illuminated the relationship between ethnicity and the growth of American churches, only rarely have professional historians focused their analytical skills on the foundational unit of American denominations, that is, the local congregation, parish, or synagogue. Similarly, immigration historians have described the contributions of this or that ethnic group to the composite …

G76-324 Limiting Feed Intake With Salt, T.D. Rich, Steve Armbruster, D.R. Gill

University of Nebraska-Lincoln Extension: Historical Materials

Cattlemen are aware of the impact high cost labor has on profit; thus, management procedures which reduce labor requirements are important. One management tool frequently used is regulating feed intake with salt.

In addition, self-feeding supplements tend to allow timid, slow-eating cows to get their share and it is an easy method of providing Vitamin A, phosphorus and other feed additives. However, there are disadvantages to feeding salt-concentrate mixes. Salt is not a precise regulator of intake since certain individuals will tolerate more salt than others and abundant water is essential.

Daily salt requirement for mature cattle is less than …

The Bryas Palace Of Theophilus, Carol Bier

Textile Research Works

According to the Continuation of the chronicles of Theophanes the Bryas palace of Theophilus (829-842) was built in imitation of an Arab palace. The present inquiry into its Islamic source offers a new interpretation of the Bryas palace within the context of Middle Byzantine secular architecture and the development of court ceremonial. ::?revious studies have concentrated upon locating Bryas in efforts to determine the extent of Islamic impact on the architecture of Byzantium. The most recent attempt, put forth by Dr. Semavi Eyice, tentatively links the unexcavated ruins at KUyUkyal!, a suburb of Istanbul, with the literary description of Bryas …

G76-308 Principles Of Beef Cattle Selection, H.A. Fitzhugh, Jr.

University of Nebraska-Lincoln Extension: Historical Materials

Selection of superior seedstock leads to lasting genetic improvement by increasing the frequency of "desirable" genes and decreasing frequency of "undesirable" genes. The definition of "desirable" varies. Nature favors genes which improve fitness to survive and thrive in the natural environment. Man should favor genes which improve biological and economic efficiency of beef production.

The concepts, definitions, formulas and symbols that are the tools necessary for effective selection programs are discussed in this publication.

G76-321 Use Of Energy Values In Ration Formulation, Paul Q. Guyer

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide contains information on the use of high energy values in ration formulation.

Ruminants digest feedstuffs primarily by fermentation in the rumen. This allows ruminant animals to use both roughages and grains as sources of carbohydrates for energy. Part of the carbohydrates pass through the rumen and are digested in the abomasum and small intestine. Most carbohydrates in feeds are converted to either acetic, propionic or butyric acid by rumen bacteria and protozoa. These short chain fatty acids are then absorbed through the rumen wall into the blood stream and eventually are used for energy in body tissue.
